Q AUTOMAT|Q FIRE-ALARM.

SPECIFICATION forming part of Letters Patent No. 252,677, dated January 24, 1882. Application filed October 25, 1881. (No model.)

To all whom it may concern:

Be it known that I, Islnon' Krrsnn, a citi-. zen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Fire-Alarms, of which the following is a specification. I

My invention relates to that class of firealarms and fire-extinguishers that are normally closed and inactive, but are brought into operation automatically during an incipient fire by the melting of fusible connections.

Referring to the drawings that accompany this specification, in which similar letters of reference in each figure indicate like parts, Figure I represents a bed-plate, to which a hinged orpivoted arm is connected, elevated by a fusible brace and fusible wire. Fig. 2 represents the same device as Fig. 1, provided with an explosive torpedo and. strikinghammer. Fig. 3 is a view of my invention having an alarm-gon g an d clapper attached. Figs. 4- and 5 represent views showing forms of mounting 'the gong and clapper. Fig. 6 is a view of Fig.

2 wherein electric connections are substituted for the alarm-gong and clapper. 'Fig. 7 is a view of my invention wherein an attached armature and electro-magnet, a gong and clapper, and explosive torpedo are operated at one and the same time.

The objects of my invention are, in case of a fire in a building, to give automatically audible notice thereof; also, to extinguish fires by the automatic discharge of water or other tireextinguishing fluids or gases.

Either form of my device'may be used separately, or any or all of them in combination, and one or more of my devices can be arranged in the separate chambers of a building, so as to be actuated simultaneously or successively.

The principal elements of my invention consist' of the device shown in Fig. 1, wherein A is a board or bed-plate, made of any suitable material, to which is hinged a swinging arm, 0, retained in an elevated position by a fusible brace, D; but the arm 0 may be retained upward by means of a fusible wire, (7, without departing from the scope of my invention. When the temperature rises to a given degree, sufficient to melt the fusible connection that retains the aim G, as showirin the drawings, it falls by gravity and actuates whatever form of V ala'rm may be attached to my device.

Fig. 2 represents myinvention appliedtothe explosionof a torpedo. In this form of the device the bed-plate Ais providedwith an anvil, a, upon which is placed a fulininating torpedo, B,and the arm carriesa hammer, c. It is manifestthat when the arm 0 falls the hammer 0 will strike the torpedo B and explode it.

Fig. 3 represents myimproved device adaptclapper is shown in Fig. 4, in which the swing-g ing arm 0 has a short vertically-depending tube, 0. The tube is closed with a cap, 0 and has a central opening at its lower end to admit the free passage of the clapperbearing stem-c c 0 are internal guide-flanges, liav ing central slots, through which the stem 0 canfreely pass. The stem 0 is a simple piece of wire, having a stnd-hrad, c, to prevent its falling through the opening in the flanges 0 and has at its terminal end a gong-clapper, c. The clapper-beating stem is extended downward through the opening at the lower end of the tube 0 by means of an extended helical spring, 0 which is coiled round the rod nearly. its. full length. The gong A may be simlarly mounted on the bed-plate A.

Another practical mannenof mounting the gong is illustrated in Fig. 5. Upon the bedplate A is a short vertical post, (d. A helical spring, a surrounds the post and extends beyond it upwardly, in order to support the inverted cup A A is a cover, in thet'orm of an inverted cup, having a stem, at", upon which stem the gong A is firmly adjusted. The inverted cup fits loosely over the post a and is kept upwardly extended therefrom by means The sudden percussion causes retraction of the springs a and c and the movable parts controlled by these springs are set in motion, causing the gong and the clapper to approach and recede from each other in continuous vibration, thus striking a succession of blows and sounding repeated alarms.

Fig. 5 is a modification in which the helical springs are kept compressed by means of fusible plugs or keys E- This character of key can be used to retain in position the movable parts of any of my devices, and in all oi my descriptions, when speaking of a. fusible support or fusible wire, I desire to be understood that a fusible retaining key or plug, E, can be sub stituted without departing from my invention.

Fig. 6 is a device containing the operative elements of Fig. 1, in whichan electro-magnet is substituted for the attached operative de vices shown in Figs. 2 and 3, the arm U being provided with an armature having the necessary wires attached to com plete a circuit, which is normally opened and closed,as the case may be. The falling of the arm makes or breaks the circuit, thus giving the alarm to suitable connections, bringing into action any of the operative devices with which the electric current is connected.

I will state that in the electric devices it is preferable to have a vibratingarmature, so as to maintain a constant alarm when the current-wire is operated upon.

Another part of my invention consists in devices which discharge a projectile, preferably explosive, t'rom the barrel of a stationary gun against a detonating-nipple attixed to atarget.

Another part of my invention consists in giving an audible alarm by the discharge of com pressed air through valves, control of which is maintained by fusible connections, and further consists in novel devices for ejection of fluid or gas from reservoirs kept normally closed by means of fusible connections; but it is not necessary herein to describe in detail or specifically claim the guns, the air-alarm, or pneumatic alarm, or explosive torpedo devices, as they are included in separate applications for Letters Patent, although it is my intention to use them in combination with the alarm devices herein described and claimed.

The manner of operating the several characters of devices herein claimed in combination is represented in Fig. 7.

I am aware that thermostats and fusible connections for automatic fire-alarms are not new with me, and I lay no claim broadly thereto.

I am aware, also, that electric local alarms actuated by rupturable connections have been used before; but the electric alarms I herein describe and claim operate not only local annunciators, but also by attached current-wires actuate alarm devices of any suitable char- 'ing where an incipient fire occurs, in which my devices are located.

' Having now fully described my invention, what I claim is-- 1. In an automatic fire alarm, the bed-plate A, provided with swinging arm 0, having suitable alarm devices attached thereto, in combination with fusible brace D, as and for the purpose intended, substantially as described.

2. Thejcombination, in an automatic firealarm, of an armature and electro-magnet connected to current-wires, with the fusible brace D, and bed-plate A, provided with soundingalarm, said bed-plate further provided with swinging arm 0, carrying a spring-borne clapper and suitable for operating both electric and other alarm devices, substanti tlly as described.

3. In an automatic lire-alarm, the bed-plate A, carrying springsupported gong A, and swinging arm 0, provided with spring-borne clapper c, in combination with fusible brace D, substantially as described.

4. In arr automatic tire-alarm operated by melting of fusible connections, the combination of the gong A, provided with inverted sliding cup A", and mounted on a vertical post, a provided with helical spring a, withtube 0, having interior flanges, c and clapper 0, con trolled by helical spring 0 substantially as described.

In an automatic fire-alarm operated by meltingol'fusibleconnections,thecombinations of the bed-plate A, having gong A, provided witlrinverted sliding cup' A, and mounted on a vertical post, a provided with helical spring a, with fusible retaining-keyE, and swinging arm 0, depending tube 0, having interior flanges, 0", and further provided with gongclapper 0, controlled by helical spring 0 substantially as described.

6. In an automatic fire-alarm operated by melting of fusible connections, the bed-plate A, provided with spring-supported gong A, and electro-magnet It, connected with currentwires, in combination with fusible brace D, and swinging arm 0, provided with armature r, and gongclapper 0, adapted, when operated, to simultaneously sound the gong and make and break electric comm unications,substantially as described ISIDOR KITSEE.
